【摘要】 通过对油菜千粒重与幼苗干重相关性分析试验 ,表明油菜种子在活力检测中 ,以千粒重的大小和发芽率高低可间接推算活力指数 ,在油菜选育、生产、经营中注重发芽率的同时选择千粒重高的种子 ,是提高种子活力的重要措施更多还原

【Abstract】 The relationship between kernel weight and dry weight of rape(B.Napus L.) was studied in lab?the result of detecting seed vigor indicated that the seed vigor index could be indirectly calculated according to the kernel weight and the percentage of germination. It is a important step to improve the seed vigor by paying attention to percentage of germination, at same time chioce the seed with high kernel weight during the rape breeding and the rape seed production and management更多还原
